I don't know what "point of center" is. It'll help your FRONT of center.

It'll also have implications on your dynamic spine. Whether they are negligible or not will depend on many things (the key's gonna be how close to "marginal" you are to optimal spine, now).

You may not see a discernable difference. It'll likely show up most in long range shots (beyond 30yds). Inside that, you may not even have to make a sight adjustment.
